Lesson 7 : Exterior And Interior Wall Ornamentation

Door and window casings

Door and window casings create a frame around the door or window opening and hide the gap between the jamb and the adjacent wall. The outside edge of the casings is usually flat, to provide surface for horizontal trim—such as a chair rail—to butt into cleanly. Slimmer trims are particularly effective in creating panels on doors and walls.
